Singapore has one of the busiest ports in the world. Ship berthing is one of the problems faced by the planners at the port. In this paper , we study the ship berthing problem. We first provide the problem formulation and study the complexity of the problem with different restrictions. In general, the ship berthing problem is NP-complete, although, some of its variants may be solved quickly. Wh...

The tremendous increase of containerized trade over the last several years, the resulting congestion in container terminals worldwide, the remarkable increase in containership size and capacity, the increased operating cost of container vessels and the adoption by liner shipping companies of yield management techniques strain the relationships between ocean carriers and container terminal opera...

Liquefied natural gas (LNG) is natural gas that has been transformed to liquid form for the purpose of transportation, which is mainly done by specially built LNG vessels travelling from the production site to the consumers. We describe a real-life ship routing and scheduling problem from the LNG business, with both inventory and berth capacity constraints at the liquefaction port. We propose a...

The management of a container terminal is a complex process that involves a vast number of decisions. The berth is the most important resource that affects the capacity of the terminal. The problem is here to allocate berths to arriving vessels and to determine which cranes in the berths process the docked vessels. For creating the berth schedule, the calling schedule of vessels, favourable ber...

Abstract Background In 2017, smaller container ports handled approximately 22% of total containerized cargo. Nowadays liner operators are calling on those with larger ships and demanding fast efficient turnaround the in port. This is possible only if berth has right capacities, working properly achieves a good productivity level. Methodology Productivity level does not depend quay crane capacit...

The ship wave generated by the passing can affect to nearby berth and moored vessels. This result in excessive motion of lead severing mooring lines, potentially causing accidents. aim this study is analyze effect ships navigating through vicinity berth, evaluate risks posed safety ship, propose measures. OPTIMOOR analysis software was utilized for assessment, with Berth A Ulsan Port chosen as ...

Both of berth allocation and quay crane assignment are one of the most complex parts in container terminal operations, which significantly affect the operational efficiency, energy consumption and operational cost of the entire container terminal. Therefore, it is necessary to develop an efficient strategy for integrated berth allocation and quay crane assignment (BACP) from the perspective of ...

This paper considers the combination of berth and crane allocation problems in container terminals. We propose a novel approach based on constraint programming able to model many realistic operational constraints. The costs for berth allocation, crane allocation, time windows, breaks and transition times during gang movements are optimized simultaneously. The model is based on a resource view w...

The berth-allocation problem (BAP) aims to optimally schedule and assign vessels to berthing areas along a quay. The vessels arrive at the port over a period of time and normally request service and departure within a time window. These time windows are usually determined through contractual agreements between the port operator and the carrier, in terms of time of departure after the vessel’s a...

After the terrorist attack on September 11, 2001 in U.S., the container security issue got high attention, especially by U.S. government, which deployed a lot of measures to promote or improve security systems. U.S. government not only enhances its national security system, but allies with other countries against the potential terrorist attacks in the future. For example CSI (Container Security...
